About this task
Attention:
• Read
“Installation Guidelines” on page 47 and “Safety inspection checklist” on page 48 to ensure that you
work safely.
• Power off the server and peripheral devices and disconnect the power cords and all external cables. See
“Power off the server” on page 62.
• Before you remove or make changes to drives, drive controllers (including controllers that are integrated
on the system board assembly), drive backplanes or drive cables, back up all important data that is stored
on drives.
• Before you remove any component of a RAID array (drive, RAID card, etc.), back up all RAID configuration
information.
• If one or more NVMe solid-state drives are to be removed, it is recommended to disable them beforehand
via the operating system.
• To ensure that there is adequate system cooling, do not operate the server for more than two minutes
without either a drive or a drive filler installed in each bay.
